I found the culprit: UnityWebAppsUtils.js (from the unity-webapps-qml
package) does this:
var script = 'import com.canonical.Oxide 1.0 as Oxide; ' +
' Oxide.ScriptMessageHandler { msgId: "UnityWebappApi-Message";
contexts: ["' +
this._WEBAPPS_USER_SCRIPT_CONTEXT +
'"]; ' +
'}';
var messageHandler = Qt.createQmlObject(script, this.webview);
messageHandler.callback = handler;
this.webview.messageHandlers = [ messageHandler ];
So it effectively overrides the webview’s existing message handlers.
